TULSA, Okla. - (TULSA - AAA Oklahoma shows that at today’s prices, E10 fuel is cheaper than 100 percent gasoline.
The blend of ten percent ethanol and 90 percent gasoline results in fewer miles per gallon, but the recent prices make it more affordable.
“Today in Oklahoma, the difference between the price at the pump for E10 and the price for so-called pure gas has grown to 30 cents or more,” said Chuck Mai, spokesman for AAA Oklahoma. “Assuming a price of $3.39 per gallon for pure gas and $3.09 for E10, you’re paying $4.80 more to fill up a 16-gallon tank with pure gas. But you’re gaining much less than that in increased miles per gallon.”
Here’s an example of how the numbers break down:
If you get 30 mpg using pure gas, then with E10, you’ll get 29 mpg, or 16 fewer miles assuming your fuel tank holds 16 gallons. At $3.39 per gallon for pure gas, your cost per mile at 30 mpg is 11.3 cents. With E10, delivering 29 mpg and at $3.09 per gallon, your cost per mile is 10.66 cents.
“As it happens, the break-even point for E10 vs. pure gas is about 11 cents per gallon when pump prices are in the range they are now,” said Mai. “If the difference between the two fuels is 11 cents or less, buy pure gas. If it’s greater than 11 cents, you’re saving money by purchasing E10.”
There are many considerations to take into account when using ethanol, ranging from impact on grocery store prices to long-term wear and tear on rubber and plastic engine components. This analysis concerned itself solely with cost to the consumer at the pump.
